A load balancing hierarchical model for micro-mobility

The design of micro-mobility management protocols stands out as an important challenge in integrating wireless networks into the IP-based Internet, especially when such networks are deployed for real-time multimedia applications. We present a new load balancing hierarchical model for micro-mobility management for the wireless access network. The scheme includes a novel anchor selection algorithm. The hierarchical model and the anchor selection algorithm enable load balancing by distributing the number of mobile hosts managed by each anchor. In addition to load balancing, the proposed scheme has the advantages of QoS (quality of service) support, robustness, scalability, and fast handoff. Simulation results of our model indicate that it provides good load balancing performance in the presence of multiple QoS classes of applications
